Diffusion and Structural Changes in High-Speed Steels Alloyed with Boron

Abstract:

The structure and phase composition of high-speed steels of different grades additionally alloyed with boron after casting, annealing, and subsequent final heat treatment (quenching and tempering) have been studied focusing on diffusion processes. In order to investigate kinetics of both the structure and phase transformations in eutectic carbides upon heat treatments, different techniques of optical microscopy, electron microscopy (both scanning and transmission ones), X-ray diffraction, and energy dispersive X-ray analysis have been used.
